Specication of Letters Patent No. 19,560, dated March 9, 18|58.

To all lwhom t may concern:

Be it known that I, JOSEPH F. HALL, of Bangor, in the county of Penobscot and State of Maine, have invented a new and useful Improved Apparatus for Raising and Lowering and Otherwise Controlling t-he Movement of Window-Curtains; and I do hereby declare that the following is a vfull and exact description of the same, reference being hadl to the accompanying drawing and references thereon, which constitute a part of the description.

The nature of the invention consists in the adaptation of a cappiece over the pulley at one end of the roller. whichshall have the effect simultaneously to cover the pulley as a protection against dust and injury and guide the cord from getting out of place and also to act as a spring bearing against said pulley to hold it in position.

In the accompanying-'drawings Figure 1 is a front view of the window curtain and the window casing in proper position, Fig. 2 is an end view of the curtain, casing, bracket roller and cord, Fig. 3 is an edge view of the spring that is to bear against the periphery of the pulley, F ig.4, is a modified bracket, Fig. 5, showing the method of attaching the curtain to the roller.

The same letters refer to the same parts in all of the figures.

That others skilled in the art to make and use my invention, may make and use the same, it is described and used asvfollows: Prepare a wooden roller or rod of suitable length for the window where it is to be used, and cut out by means of any suitable tool a pear shaped groove from end to end as shown in Fig. 5 where is seen a section of said groove which is circular on the lower side and runs almost to a knife edge at the periphery of the roller. A corresponding shaped rod as seen in section at (a)k is slipped into the hem of the upper part of the curtain, and the rod and hem are thrust 'thro-ugh the pear shaped groove, andthis makes the fastening of the curtain to the roller, A.

The frame B, B, Fig. l, shows the window casing to which the brackets D, D, are screwed, by screws (a). The caps or ends of the roller are generally of harder wood than the body of the roller. That on the pulley end is generally glued on, while that on the opposite end, is so made as to receive the end of the roller into a cup shape cavity, ,and is thus pinched firmly in its place.

A front view of brackets D, D,.1nay be seen in Fig. 1, and a view of the flange part, or elevated edge, may be seen at D Fig. 2. This projecting part forms a bearing for the pintle, or arbor of the roller A, as is seen in Fig. 2, while the flat portion shown in Fig. l, is screwed to the front face of the casing by screws (n). Upon this front face of the bracket is placed, flatwise, the spring E, and riveted in its place by the rivet (It). A side view of said spring may be seen in Fig. 3, and the upper and lower part of it in Fig. 4, where it is bent over against the periphery of the pulley It is the use and adaptation of this spring that constitutes the prominent feature of the invention claimed. It is the spring in this particular position and the functions performed by it. It is the spring performing the double function of covering the pulley from dust and injury, and at the same time having a bearing against its periphery and sustaining the curtain roller and curtain in any position in which it may be placed by pulling the cord (0,) or cord (g). The spring E, also acts as a shield and guide to the cord to keep it from .getting off the pulley, and also in aiding to put up the apparatus in its place, which last operation is performed as follows: Havin made the brackets on each side of the window fast in their places, put the pintle (p) in its bearing and then carry the pintle (g) closely against the lower part of the projecting flange D, and then carrying it upward following the edge of the flange and pushing up the spring till the pintle (g) drops into its bearing, when the spring' hugs the periphery of the pulley and the curtain is in condition to be worked.

lThe bracket D is usually made of cast brass or iron and the spring of rolled or sheet metal and then riveted tol the face of D. This being somewhat expensive I have occasionally manufactured the bracket by cutting out of a piece of sheet metal with a suitable tool the bracket piece (D) seen in Fig. 4, the disk portion being turned up at right angles with the body (c, 6,) and the part c being bent into a curve to hug closely the curtain roller. This last mode of making the bracket is specially fitted for a cheap curtain fixture, but for liner and better nshed Work the rst described is preferable.L

Having fully described the nature of my invention and the several modes of constructing the devices, and operating the same, what I claim as my invention and de= sire to secure by Letters Patent is- The combination of the spring (E) and the pulley (i) substantially as set forth.
